Using The Dma - Epson EPL-5700 Reference Manual

Using the DMA

Faster printing with a Direct Memory Access (DMA) is possible
if your printer is connected to your computer through an
Extended Capability Port (ECP), a type of parallel port with
expanded specifications. With the DMA and the ECP, you can
send print-job data directly to the printer without going through
the CPU, which increases the effectiveness of data flow.
Before using DMA to transmit a print job confirm the following
points.
Check if your computer supports DMA. To confirm if your
computer has an ECP chip installed, contact the manufacturer
or look in the computer's documentation.
Confirm the parallel port setting is "ECP" or "ENHANCED"
through the BIOS Setup. Refer to your computer's
documentation to set the BIOS. However, before setting the
BIOS, uninstall the EPL-5700L/EPL-5700i printer driver.
After setting the BIOS, re-install the printer driver.
Confirming if you can use DMA
Using DMA increases your printing speed. You can confirm if
your computer can use DMA by checking the Optional Settings
tab under Properties in your Printer driver.
